Question Analysis

This question involves the concepts of vertical angles and linear pairs of angles formed by two intersecting lines.

Key Concept Explanation

Vertical angles: When two lines intersect, vertical angles are the pairs of opposite angles. They are congruent.

Linear pair: A linear pair is a pair of adjacent angles formed when two lines intersect. The sum of the angles in a linear pair is .

Step - by - Step Solution

1. Examine the position of angles and :

Angles and are adjacent angles as they share a common side and a common vertex.

They form a straight - line along one of their sides. So, they are a linear pair.

They are not vertical angles because vertical angles are opposite to each other, and
